How Are Masterbatches Increasing Output in Packaging Solution?

A packaging is covering over a product to increase its shelf live and maintain quality. The package needs to be appealing, durable, and airtight to prevent contamination of product inside. The packaging industry is playing a crucial role in the food, beverage, and packing of essential items to prolong their shelf life before reaching to consumers. Further, the appealing design and colour on a package increase the commercial value of a product.

Significance of polymers in the package solutions

Plastics are one of the most common materials used in the packaging industry. The raw polymers are natural to mould and process to make into different shapes. Further, properties of raw polymers can be easily enhanced with the addition of strength, colour, compatibility, and stiffness needed in this sector. Thus, polymers have always been a chosen material in the packaging solution.

What is a masterbatch?

Masterbatch is a solid or liquid material used to impart colour to the base polymer in processing. However, the role of a masterbatch goes beyond adding colour to the plastics. It can act as an additive and carrier resin to change the mechanical properties of a finished product. Hence, here are three types of masterbatches available in the polymer industry:

Colour masterbatch used to add hues to any product.

Additives make a change in the functional and mechanical properties.

Special effects additives help in increasing output and other functions such as slipping agent, anti-fog, anti-abrasion, UV rays stabilizers, and others.

Which are the popular masterbatches used in packaging solutions?

The selection of an additive takes place based on a compatible base polymer and outcomes wanted in a product. Incompatible additives won't help achieve the goals of a manufacturer in the polymer processing. The TPU masterbatch works best in the processing of TPU film instead of processing other base polymers. There is a need to analyze a polymer before selecting any additive for a process.

BOPP Masterbatch

BOPP stands for Biaxially Oriented Polypropylene. It is a film stretched mechanically and through cross direction technique. The film produced with the BOPP as the base material has excellent gloss, transparency, resistant to moisture and harmful chemicals, dimensional stability, and other uses. However, the most popular use of a BOPP masterbatch takes place in high-speed printing giving optimum output to a manufacturer. There is a growing use of this film due to its capability of recycling. Thus, it is one of the most popular choices for printing and packaging solution for processors around the globe.

BOPET Masterbatch

BOPET stands for Biaxially Oriented Polyethylene Terephthalate. It is a polyester film produced by the PET. There is a growing use of this film due to its tensile strength, chemical and dimensional stability, reflectivity, and gas and aroma barrier properties. The BOPET masterbatch has high applications in the fabrics and packaging solution, acting as an anti-blocking agent in the reel.

Conclusion

The packaging industry is flourishing due to the use of many polymers. Masterbatches add the desired properties and functionalities in the package to improve their shelf life. Thus, most of the plastic processors are using them in the plant nowadays.
